Additional information

These surfaces have been developed by the British Geological Survey as part of the iHydrogeology project (a co-funded project between BGS and the Environment Agency). It was developed, in partial fulfilment of work package 3 of the iHydrogeology project, with the aim of providing a tool to visualise regional-scale spatial and depth relationships between Principal Aquifers in England and Wales and potential shale gas source rocks.

Statement

The original surfaces were derived from the National Geological Fence Model. Data from crossections was extracted and interpolated in order to create the surfaces. The top surfaces of the shale gas source rocks were produced from the GB 3D fence diagram (v2012) using GSI3D and GOCAD software. The top of the shale gas units were identified from the cross-sections and grouped based on information provided by Geologists, e.g Upper Jurassic Clays. The cross-section correlation lines from the sections were exported as pline files from GSI3D and imported into GOCAD. Using a combination of the DigMap 1:625 000 Bedrock Map (V5) to constrain the units at outcrop and the correlation points from the GB 3D cross-sections, surfaces were generated using the Discrete Smoothing Interpolation in GOCAD. The subcrop was constrained by the spatial extent of these units identified in cross-section. Surfaces were exported and converted to ESRI grids at 3000 m cell size.
